chore(ci): also deploy `code-angularjs-org` to Firebase

Previously, we only deployed the built files to Google Cloud Storage for
the `code-angularjs-org` Firebase project. This meant that the other
Firebase services (such as functions, hosting, storage) were not updated
when we made changes to their source code or configuration.
(This isn't a problem at the moment, since the code/configuration for
these service changes infrequently, but could bite us in the future.)

This commit fixes this by ensuring that we deploy to all enabled
Firebase services (currently functions, hosting and storage).
